STEAMSHlP-FURNAGE.

Specification ofLetters Patent.

Patented Oct. 28, 1913..

Application filed August l?, 1912. i Serial No. f715,576.

To all LU/72.07211, t may concern Be it knownthat l, CI-Iannns A.K'UENZEL, a citizen of the United States, residing at lhiena Vista, inthe county oi" Chaffee, State of Colorado, have invented a new anduseful Steaniship-Furnaee, ot which the following is a specification.

My invention consists of an improved gasgenerator and iurance for theboilers of a Steamship employing oil as a fuel.

lt further consists oit improvedmeans for protectinpd the generator..

lt further consists ot improved means tor distributing the oil.

It further consists ot other novel features ot construction all as willbe hereinatter fully set forth.

'lhe invention is satisfactorily illustrated in the aceompanyingdrawing, but the im port-ant instrumentalities thereof may be Varied,and so it is to be understood that the invention is not limited to thespecilic arrangement and organization shown and described.

Figure l represents a somewhat diagrammatic side elevation et portionsot the hull otl a steamship equipped With my improved gas generatingapparatus. Fig. 9. represents an enlarged sectional View of thegenerator.

Similar numer ls ot reference indicate corresponding parts in thefigures.

Referring to the dra-Wings, the roter-ence numeral l indicates the hullet a stearnship, in which one or more boilers, 2, of any desired orrequired type are mounted in any suitable or desired manner. The boilerhere illustrated is ot the return-tine type, haring a furnace, 3, abottom-tine 4l, a return-cham ber 5, tlues, (3, and a smoke-chamber, 7,trom which a stack, 8, extends. rlhe bottom-flue has a lining, 9, ofrefractory material, such as irebrick, in its under side to retain theheat from the products of combustion pass ing through the flue and toprotect the bottom of the boiler. An ailhcoinpressor, 10, driven bysteam, internal combustion, or by any suitable power, is arranged tosupply air under pressure to a tank, ll, and oiltanlrs, l2, are arrangedpreferably in pairs, below the level ot the furnace oit the boiler. Anair-pipe, la, leads from the air-tanlr and is connected by branclrpipes13 and le", to necks, l5, upon the tops ot the oil-tanks and havingIcontrolling Valves 1G, at such connections. The contents of the oiltanks may Vper one, 21, cnstitutes a ifaporiZing-chainthus be subjectedto airrpressure. Pipes, 17, project through the necks of `the tanks tonear the bottoms ot the saine, and areconnected to a common oil-supplypipe, v18, values, 19, controlling' such connections. Aretort-structure, 20, is supported in thefiiredoor opening oit theboiler-furnace, and is ot' the same construction as that disclosed inthe Patent No. 1,039,549, issued-tome on September 24th, 1912, uponapplication, Se rial No. 646,258, tor gas Lgenerator, filed by. me onAugust 26th, 1911, and needs no specific description. Generally, suchstructure has tour horizontal chambers, the upber, the second one, 22,an air-heating chan1 ber, the tnird one, Q3, a superheating retort, andthe fourth one, 24, a distributing retort, from which burners, 25,extend into the boiler-turnace- Air under pressure is conveyed trom theair-distributing pipe, la, through a pipe, Q6, to an atomizer, Q7,receiving oil :trom the oil-distributing pipe 18 through a pipe, 28, andsaid atomilaer in jects a jet ot mixed oil and air into one end of thevaporizing chamber, from the other end ot which the Vapor passed throughpipe, 29, to a comminuting and mixing device, 30, fully described andillustrated in my said above patent application. Compressed air isconducted through a pipe, 3l, to one end of the air-heating chamber, 22,in which it is heated and then conducted from the opposite end ot thechamber, through a pipe, 32, to the comminutin?,` and inixing device,and there mixed with the heated vapor and conducted through a pipe, 38,to the superheating retort, where the is superheated and passes to thedistributing retort and out through the burners to be consumed in thefurnace. The retort-structure is so supported in the tire-door opening,that a space, 34, is lett open beneath the structure for admittingatmospheric air into the furnace. A checker-Work, 35, of firebricks,having openings between them is secured by a plate, 36, and bolt, 37, tothe tace of the retort-structure to protect the same from the excessiveheat ot the iiame in the turnace, While the bricks Will transmitsuticient heat to heat the chambers and retorts and the `gases therein.

TWhen the burners are lighted after the generating apparatus has beenstarted, the flame and products of combustion will be carried around theboiler and through the boiler iues, and atmospheric air is adinittedthrough the passage beneath the retortstructure to the flanies in thefurnace, aiding combustion and increasing the heat of the iarnes by theadded amount of oxygen.

One oil-tank may be lled While oil is being forced out from the othertank, so that there need be no interruption in the operation of theapparatus While the oil-supply is renewed, nor need the tank be filledWhile there is pressure in the saine. By having' the oil-tanks beneaththe level of the burners and retort apparatus, there can be no floodingof the furnace from gravity if by accident an oil-valve should be openedafter the apparatus is stopped, as is liable Where gravity feed isemployed.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent, is

l. 1n an apparatus of the character stated,

a retort-structure adapted to fit in the firedoor opening of a furnaceand comprising a vaporizing chamber, an air-heating chamber andsuperheating retorts, a burner extending into the furnace and connectedto receive gas from said retorts, and a checker- Work of rebrick andsupported against the inner face of said retort-structure.

2. In an apparatus of the character stated, a furnace having a fire-dooropening, a retort-structure secured to it in and partly close the upperpart of said opening and thereby forni an air-inlet beneath it andconstructed with air and gas heating chambers, burners extending intothe furnace from said retort-structure, and a iirebrick checker- Worksupported against the inner face of said retort-structure.
